چکیده
Development of ceftriaxone loaded nanostructured lipid carriers to increase permeability across uninflamed meninges after parenteral administration. Lipids were selected by theoretical and experimental techniques optimization NLCs done response surface methodology using Box-Behnken design. The Δδt for glyceryl monostearate Capryol90 4.39 2.92 respectively. drug had maximum solubility 0.175% (w/w) in glycerol 2.56g dissolved 10mg drug. binary mixture consisted a ratio 70:30. optimized particle size was 130.54nm, polydispersity index 0.28, % entrapment efficiency 44.32%, zeta potential -29.05mV, loading 8.10%. In vitro 5.06x10-6 cm/s; evidently, the pervaded through meninges, which, further confirmed from vivo biodistribution studies. concentration between brain plasma 0.29 that solution 0.02. With 44.32% enhanced 7.9 times compared with solution. DSC XRD studies revealed formation imperfect crystalline NLCs. improved resulting better management CNS infections.

Nanostructured lipid carriers loaded with resveratrol modulate human dendritic cells
Dendritic cells (DCs) are promising targets for drug delivery, as they can induce immunity or tolerance. The current study aims to examine the potential of using nanostructured lipid carriers (NLC) as delivery systems for human DC by evaluating nanoparticle internalization, cell labeling, and drug activity. NLC were formulated incorporating the fluorochrome fluorescein isothiocyanate (FITC-NLC)...
متن کاملEffect of surfactant on lycopene-loaded nanostructured lipid carriers.
Nanostructured lipid carriers (NLC) have gained high interest as enhancing drug delivery systems via topical application during the last few years. NLC can enhance stability of many active substances against environmental stress. The extremely small size of NLC plays an important role in skin penetration. The unchanged size of NLC upon storage indicates its physical stability. The aim of this w...
متن کاملZerumbone-loaded nanostructured lipid carriers: preparation, characterization, and antileukemic effect
Zerumbone, a natural dietary lipophilic compound with low water solubility (1.296 mg/L at 25°C) was used in this investigation. The zerumbone was loaded into nanostructured lipid carriers using a hot, high-pressure homogenization technique. The physicochemical properties of the zerumbone-loaded nanostructured lipid carriers (ZER-NLC) were determined. The ZER-NLC particles had an average size of...
متن کاملNanostructured Lipid Drug Carriers
solid lipid carriers – NLC. Particulate lipid matrices in the form of lipid pellets are known from the textbooks since many years, products are on the market (e. g. Mucosolvan retard, Boehringer-Ingelheim). After these lipid pellets as the first generation, P. Speiser developed so-called “lipid nanopellets for oral administration” in the middle of the eighties [1]. This system was not further d...
